Replace sys.stdout with an object that stores the lines printed. (Due to
the way the print statement works, you should not inherit from file)
class PrintBuffer:
def __init__(self, stream):
self._stream = stream
self.output = []
def write(self, text):
self.output.append(text)
self._stream.write(text)
def __getattr__(self, name):
return getattr(self._stream, name)
py> import sys
py> sys.stdout = PrintBuffer(sys.stdout)
py> print "Hello world!"
Hello world!
py> print 2,"*",3,"=",2*3
2 * 3 = 6
py> print >>sys.stderr, sys.stdout.output
['Hello world!', '\n', '2', ' ', '*', ' ', '3', ' ', '=', ' ', '6', '\n']
py>
